You cannot continue driving with a damaged oil cooler. This is because the oil can reach extremely high temperatures under such conditions, leading to increased oil evaporation in the oil pan and higher oil consumption. Oil also plays a cooling role, and its failure can cause the engine to overheat. In this scenario, the oil temperature will rise excessively, reducing its viscosity and compromising its lubrication effectiveness. Additional Information: Precautions: The oil cooler used in cars is a component with a relatively high failure rate. After the oil cooler is damaged, the most common symptom is excessively high oil temperature. If the oil temperature is too high, it not only accelerates oil consumption but may also lead to oxidation and deterioration of the oil.

If the oil cooler is broken, I strongly advise against driving. The oil cooler's function is to cool the engine oil and prevent the engine from overheating. Once it fails, the oil temperature will rise rapidly, leading to poor lubrication, increased wear on internal engine components, and even the risk of cylinder seizure or fire—it's extremely dangerous. With decades of driving experience, I've seen many cases where people insisted on driving, only to break down midway, resulting in repair costs skyrocketing. Safety should always come first. Stop the car immediately for inspection. If you notice the oil temperature gauge rising abnormally, shut off the engine and call for a tow truck to a professional repair shop. Don’t forget to check the cooler lines and oil condition during regular maintenance—it can save you a lot of money.

What does the exclamation mark on the Volkswagen T-Roc dashboard mean?

There are generally three types of exclamation marks that may appear on the Volkswagen T-Roc dashboard, with specific explanations as follows: Yellow triangle symbol: A yellow triangle with an exclamation mark in the middle is the TCS (Traction Control System) indicator. This light serves as a reminder to turn off the traction control system. If it lights up and remains on while the traction system is active, it indicates an issue with the TCS. Yellow brackets: Yellow brackets with an exclamation mark in the middle represent the tire pressure monitoring indicator. This light indicates that the pressure in one of the tires is insufficient, and you should visit a tire shop or a 4S store to check the tire pressure. Yellow gear: A yellow gear with an exclamation mark in the middle is the automatic transmission fault warning light. This indicates a problem with the transmission, transmission lubricant below the normal range, or the need for lubricant replacement.

How to Read the Date on New Car Tires?

On the sidewall of the tire, locate the string of characters starting with the English letters "DOT". At the end of these characters, there will be a four-digit number enclosed in an oval border, which represents the tire's production date. The first two digits indicate the week of the year the tire was produced, while the last two digits represent the production year. Here is some related information about tire maintenance: Daily Tire Pressure Check: Avoid having tire pressure that is too high or too low. Overinflated tires may risk a blowout under high-speed operation due to inability to withstand excessive expansion pressure, while underinflated tires may experience excessive flexing due to uneven road surfaces during driving, keeping the tires in a state of fatigue and accelerating aging. Regular Tire Rotation: Cross-rotating the front and rear tires ensures even wear across all four tires and provides better friction between the front wheels (steering drive wheels) and the road surface, preventing front-wheel slippage and ensuring driving safety. Regular Balance Checks: Regular balance testing not only extends tire life but also improves the vehicle's driving stability. Timely Replacement: It is recommended to replace tires after approximately 40,000 kilometers of use. If driving conditions are excellent, this can be extended to 60,000 kilometers, but tires older than two years should also be replaced.

Where is the position light located on the new Sylphy?

The position light of the Nissan new Sylphy is located next to the headlights, at the outermost lights on the front and rear of the vehicle. Position light: The location of position lights varies depending on the vehicle model. On small cars, position lights are commonly referred to as small lights. On larger vehicles, due to their size, the lights on the front and rear sides are called position lights, commonly known as side lights, which belong to the category of small lights. Their main purpose is to indicate the presence of the vehicle and its approximate width, making it easier for other vehicles to judge during overtaking or meeting. Rear position light: Generally, rear position lights use red light sources to enhance light penetration. In fact, during hazy weather, driving at dusk, or in drizzling rain, you can turn on the position lights alone without needing to turn on the low beam headlights.

What causes the Audi A6L to shake when reversing in cold conditions?

Here are the specific reasons why the Audi A6L shakes when reversing in cold conditions: Suspension system malfunction: The suspension system is primarily responsible for filtering the vibrations generated by the engine during operation. If there is an issue with the suspension, these vibrations will be directly transmitted to the steering wheel and the cabin, affecting the driving experience. When the engine is idling, turning on the vehicle's electrical systems can also easily cause shaking. The engine's load increases due to the activation of electrical components, leading to a drop in idle speed. To compensate for the shaking caused by the drop in idle speed, the engine will automatically increase the RPM. Unstable oil pressure: Check whether the fuel supply pressure and the intake pressure sensor are functioning normally. If the fuel pump's supply pressure is abnormal or the intake pressure sensor's readings are incorrect or malfunctioning, it can cause the vehicle body to shake.
